Of course voting matters. We recognize the winners of votes.
You might not like the way votes turn out, and you might argue that corporations press us to vote certain ways, or that we are misinformed and so we vote based on misinformation, or you might raise a ton of other similar complaints, but at the end of the day the most important part stands:
We still respect the results of elections.
The people still get what they vote for, even if they may vote for a really really really really really really really stupid things based on really really bad influences, if you must.
